A front door answering intercom system equipped with video offers many features that add to the security of your home. The camera situated on the front of the intercom allows you to view any visitors and decide if they are someone you know, or who you want to keep out. With just audio features, you might not get the full picture of who is at your door, but with included video capabilities, you can have that added layer of protection.
I haven't had to change the bag in my vacuum yet, but it appears to be easy enough and I like the fact that the hose end to the vacuum unit does not have to be removed in order to change the bag. This is another reason why I don't like the ProLux Terra Vacuum, very hard to replace the bag.
